To all whom it may concern:

Be it known that I, NELSON E. FUNK, a citizen of the United States, residing at Montclair, county of Essex, and- State of New Jersey, have invented certain new and useful Improvements in Transfer-Printing Machines, fully described and represented in the following specification [and the accompanying drawings, forming a part of the same.

This invention relates to improvements 111 transfer printing machines.

In transfer printing machines of the rotary type, the transfer cylinder is, of course, arranged between the type or plate cylinder and the impression cylinder. Machmes of this classinclude a throw-ofl' mechanlsm, the purpose of which is to move the transfer cylinder out of contact both w th the type or plate cylinder and with the lmpression cylinder, when 'a sheet falls to be fed between the transfer cylinder and the 1mpression cylinder. If the transfercyl nder is left in contact with the type cylinder when a sheet is not passing through the ma chine, there is liability that too much lnk will be set off onto the transfer prmtmg surface, and if the transfer cylinder is left in contact with the impression surface, the design will be imprinted upon the blanket. In some transfer printing machines as heretofore constructed, the transfer cylmder is left stationary and the throw-off mechanism operates to move. both the type or plate cylinder and the impression cylmder. This method of operation requires cumbersome and expensive mechanism for its operation. In another class of transfer printmg machines, the throw-oli' mechanism operates to move the transfer cylinder, the type and 1mpression cylindersbeing held stationary, the throw-off mechanism including eccentnc bearings for the transfer cylinder shaft,

these bearings being mounted in the usual stationary boxes. While this method of operation has the advantage of moving only a single cylinder, it is objectionable because the cylinder shaft moves in the are of a 'circle and this requires that the center of the transfer cylinder shaft shall be located Well to one side of a line connecting the centers of the printing and impression cylinders. In most printing machines, however, it is desirable that the centers of the printing, transfer and impression cylinders be located mechanism to vbe hereinafter described,

substantially in the same straight line, or as nearly in the same straight line as possible, and in some classes of machines, such an ar rangement is practically necessary on ac-' count of the character of stock to be printed. The present invention has for its object to produce an improved mechanism-for moving the transfer cylinder of transfer printing machines of the rotary type out of contact with the printing and impression cylinders, this mechanism being of such a character as toenable the centers of all the cylinders to be arranged nearly in the same straight line. With this and other objects in view, the invention consists in' certain constructions and in certain parts, improvements and com binations as will be hereinafter fully described and then specifically pointed out.

Referring to the drawings which illustrate one embodiment of the invention:' Fig ure 1 is a side elevation of so much of a transfer printing machine embodying .the invention as is necessary to an understanding thereof. Fig. 2 is an enlarged detail sec- 22-of Fig. 1. Fig. 3 is a tion on the line similar section on the'line 33 of Fig. 1. Figs. 4 and 5 are end elevations, partly in section, of certain parts of the throw-0d mechanism, the two figures illustrating the in difierent stages of the operation. I

Referringto the drawings, 1 indicates a part of the side frame-in WhlCl'l the various cylinders are mounted, and 2 impression cylinder, fthis cylinder being mounted on a shaft 3 supported in suitable boxes 4 adjustable vertically to regulate the impression by means of the usual adjusting mechanism indicated at 5. The type or plate cylinder is diagrammatically indicated at 6, and it will be understood that the cen-' ter of the shaft of this cylinder is in the same vertical line as the center of'the shaft indicates the.

3. The transfer-cylinder is indicated at 7'.

In machines embodying the invention the transfer cylinder will have its center substantially -or nearly in the line connecting the centers of the plate and impression cylinders, and in" order that this may be effected, the transfer cylinder will be mounted in such away that the throw-off mechanism, will move it in substantially a right or straight line. While the construction by which this movement is efl'ected may be varied,.in machines'embodying the invention in its best form, the shaft 8 on which the transfer cylinder 18 mounted,

will be supported in sliding boxes 8. In the particular construction illustrated, these sliding boxes are guided in'their movement by ways 8" which are formed on the machine frame.

- The particular mechanism for effecting the right or straight line movement of the transfer cylinder may be variedwithin' wide limits. In the particular construction illustrated, this mechanism includes (see Fig. 3) a rotary actuator comprising a shaft 9 suitably supported in the frame and extending across the machine from side to side. As illustrated, this shaft has connected thereto by means of a feather 10 an eccentric sleeve 11 rotating in a collar 12 formed on one end of a'connecting rod 13. This rod 13 has a collar 1 1 formed on its other end, this collar comprising a bushing 15 in which the shaft 8 is mounted. The collar 14 is held inposi- 'tion' by a cap 16 and the collar 12 by a flange 17 formed on the sleeve, 11, the sleeve being held in position by a cap 18. It will be understood that'there is a sleeve and a connecting rod 13 with itscollars on each side of the. machine, but as the constructions are identical, only one side of'fhe machine is shown. 'It-w'ill be obvious that with this construction when the shaft 9 is rotated the boxes in which the transfer cylinder shaft is mounted. will be given a right line movement for movingthe transfer cylinder out of-contact with both the impression and type or plate cylinders.

The operating. means for the actuator may be varied and will be varied according to the type of actuator employed. The means, however, should be of such a characteras to be'under the control of the operator so that the machine may be tripped, that .is, the

transfer cylinder moved, when necessity therefor arises.- In the'particular construction illustrated, the actuator shaft is provided with a collar 19 formed onthe' end'of' a sleeve, 20 connected to theactuator shaft bymeans of the feather 10. This collar 19 'is provided with notches 21, 22 which are arranged to be engaged at proper times by apawl 23 pivoted at 24 on a pawl carrying arm 25, extending from a toothed hub 26' loosely mounted on the "shaft 9, The teeth on the hub. 26 are in engagement with the teeth of a segment 27.; pivoted toa stud 28 y The inner end of this segment lever carries a roll 29 which runs in a ,cam groove 30 formed in a cam 31 fast to the end of the transfer cylinder With this construction it will be understood that as the transfer cylinder rotates the segment lever 27 will be'rocked on its pivot and will effect an oscillating motion of the pawl .carrying arm from the position shown in Fig. 4 to the. position shown in-Fig. 5. It will be further understood that if the pawl 23 is free to engage either the notch 21 or the notch 22 of the disk 19, it will effect a movement of the actuator shaft. In the normal operation of the machine, however, the pawl carrying arm and the-pawl move idly.

In the best constructions embodying the invention, the means for permitting the operation of the actuator may be varied and will vary according to the means selected for effecting its operation. In the particular construction illustrated, there is provided a release mechanism comprising a collar 32 located alongside the disk 19 and embracing the sleeve 20 on which the disk is formed, this collar having a high part 32' which extends beyond the periphery of the disk 19. This collar has formed in one piece with it a'bent arm 33 to which is pivoted a connecting rod. 3& extending through a guide fast to the inside of the frame ofthe machine. This rod is connected at its lower end to an arm 36 on a treadle shaft 37, the treadle on the shaft being marked 38. A spring 39 surrounds the rod 34 and holds it in such treadle the collar is swung into the position shown in Fig. 4, in which position the pawl '23 is free to and will engage the notch 21 or 22, according to whichever one is in proper position. The pawl having engaged the notched collar, will rotate the actuator shaft 9' and through the connections described move the transfer cylinder.

The machine should not be tripped except. between cprintings, and in order to prevent the operator from tripping except at. the proper time, the shaft 37 may be provided with an arm 10 to which is pivoted a rod 41, this ro'dha ving a slot 42 which engages a erankpiii 4.3 on the end of the shaft3..- I

A' lockin mechanism may be provided to prevent t eactuator shaft from being accidentallyimoved. While this mechanism may be 'vanied,"in the particular construcin the frame of'the machine. This pawl is in the form of a bell-crank and its arm 48 is connected to a spring rod construction ,49 of the usual :type. The unlocking of this locking; mechanism may be effected by mecliamsm ofla suitable type, it being unmachine for derstood that the mechanism will vary according to the type of lock employed. As shown, the pawl 46 is provided with a roll 50, which is arranged to engage the high part 32 of the collar 32 before referred to. When the'operator, therefore, steps upon the .treadle and swings this collar, he not only uncovers a notch to be engaged by the pawl 23 but he also releases the locking pawl.

It will be seen that the foregoing mechanism is an exceedingly efiective one for accomplishing the purposes for which it is designed, and, further, that by moving the transfer cylinder in a substantially right or straight line, the center ofthe cylinder can be brought nearly in line with the centers of the plate and impression cylinders. Theoretically, of course, the transfer cylinder touches the other two cylinders along one line only, but practically, and especiall in view of the fact that the transfer cylinf der has a soft covering, it has considerable surface in contact with both cylinders. To avoid any wiping action as the transfer cylinder is moved, therefore, its center should be located slightly to one side of the line which connects the centers of the other two cylinders.

Changes and variations may be made in the construction b which the invention claimed is carried into effect, The invention claimed, therefore, is not to be confined to the particular construction herein described and illustratedin the accompanying drawings.

What is claimed is:

1. In a transfer combination with the ty e, transfer and impression cylinders, sai cylinders having their centers in substantially the same straight line, of means operatively connected with the driving mechanism of the giving the transfer cylinder a right line movement to move it into and out of contact with the type and impression cylinders.
